Windows Agent connect but it's node shows as down

I solved my own problem by deleting the node and re-adding it with the Agent method of polling. It was a shame to lose the device history, but it did stop the "node down" alerts.

I'm having this same issue, I tried deleting and adding back. The node stayed up for the first minute or so then went down. It's very odd because it's using the Status and Response time agent for status polling. Agent connection and plugins are all green and up to date. I can even list resources and see all the drives and interfaces so I know it's communicating, just status will not update.

I have resolved the issue changing to Status & Response Time Agent from ICMP.
